Step 325: 39528 + 122 = 39650
Step 326: 39650 + 122 = 39772
Step 327: 39772 + 122 = 39894
Step 328: 39894 + 122 = 40016
Step 329: 40016 + 122 = 40138
Step 330: 40138 + 122 = 40260
Step 331: 40260 + 122 = 40382
Step 332: 40382 + 122 = 40504
Step 333: 40504 + 122 = 40626
Step 334: 40626 + 122 = 40748
Step 335: 40748 + 122 = 40870

So, 122*335 = 40870
